` one within the other, so as to form a space between them, except at the top, which is filled with asbcstus or other non-conducting material, and is charged with hot-balls or other `forni of metal, for heating the car or other room by radiating the heat contained in the said objects, and in the top of the heater is a register, and in the bottom an opening for allowing the air to How in to be heated and be discharged at the top, by which the heat may be given ott' more or less rapidly according to the volume of air allowed to pass, which can The register may be in the'inlet-passage at the bottom, if preferred.l

This improved heater is designed mainly for cars and carriages; but it may also be used for heating rooms temporarily in hotels. The

vhot-balls will be supplied to the cars at the stations, and may be introduced through a door in the top or side, as preferred.

For street-cars the heater will preferably stand on the floor like a stove; but for railf way-cars it may belet down from the door,

Figure l is a top view of-my improved heater, with the cover'raised and Fig. 2 is a transverse section taken on line :u :v of Fig. l.

' Similar letters of reference indicate correponding parts.

A is the outer case; B, 'the inner one; C, the space between them to be filled with asbestus 5 D, the heating-cylinder or other form of metal, to be heated in a furnace at the station, and be put in hot. E is thecover of the heater, whichin this case contains the register F, and G is the inlet for air at the bottom of the heater. The heat generates au active current of air from below, which takes up the heat and carries it ott' into the room more or less rapidly, according to the size of the openings to be regulated by the register, by which they will be graduated according to the heat of the cylinder D, or other pieceor pieces employed for the purpose.
